G012-S: Error AC OVP: AC Voltage too high

The measured voltage on the AC Grid connection is (after 10 sec) too high (>270Volt).

  1. Check the grid voltage, is it in range?
  2. Check the fuses, is everything in order?
  3. In case a backup relay was used, check the wiring, everything should be connected as according the PowerRouter installation manual.
